b) The molality of the hydrocarbon is 0.265 M
c) Mass of cyclohexane is 0.014354 g
d) The number of moles of hydrocarbon in the solution is
e) Molar mas of hydrocarbon is .
Explanation:
a)
Therefore, Change in temperature of the freezing point is +5.35C.
b)
Therefore, The molality of the hydrocarbon is 0.265 M.
c)
Therefore, Mass of cyclohexane is 0.014354 g
d)
Therefore, The number of moles of hydrocarbon in the solution is
e)
Therefore, Molar mas of hydrocarbon is .

The discovery of protons can be attributed to Rutherford. ... Given the discoveries of electrons in 1897 by Thomson, Rutherford and other scientists decided that a positively charged particle must exist to center the electron to create equally neutral atoms. Thomson proposed the name 'positive rays'.
